How Much Would You Charge For This?

Someone asked me to make a cakelike this with this edible image on it. After I told her it was an edible image she decided she did not want an edible image. I offered to cut the image as close as I could get it out of fondant. I have about 5 hours in Dora, Boots the monkey, & flowers. Already had fondant colored thank goodness! I considered myself to be pretty quick. I need to think about that again LOL! My question is how much would you charge for this cake?
